Success! Setting it to queue seems to work great, i have it set to -q1m for
sendmail. Ive rewrote sendmail.logs.pl a bit you guys might be interested
in.
run ./stats.pl right from console for nice stats on whats goin on with your
mail gateway

My incoming queue is now less then 50 or so at all times, with SA 2.0 fully
enabled and RBL checks.
